We use JFFS2 on both an ARM9-platform and on our own CRIS platform. We
never unmount the device in preparation for power down; when someone pulls
the plug, the system just dies. While we do occasionally see warning
messages about incomplete nodes during the next boot-up, we have never
experienced anything as severe as you mention, and we have not lost any
files on the JFFS2 filesystem either.
